ilnite States LIQUID DISPENSING CONTAINER Harry E. Dennie, NewtownSquare, Pa., assignor to Chase Bag Company, New York, N. Y., acorporation of Delaware My invention is an improved liquid dispensingcontainer for carrying, storing and dispensing fluids'such as milk."

During recent years the rules and regulations of the health governingbodies of various municipalities and states concerning the dispensing offluid milk in small quantities have resulted in the modification of thestandard steel milk can to provide means at the bottom thereof foremptying the can into a glass or other small receptacle. Such'cans arenormally placed in a cabinet such as that illustrated in Patent No.2,601,319. However, the steel can has a high initial cost and must beretinned regularly. It also involves the various steps of returning thecans to the dairy and processing the empty cans before refilling withfresh milk.

The primary object of my invention is to provide a light Weight,disposable container which can be used for the storage, transportationand dispensing of milk or other liquids in relatively small amounts,that is to say, in three and five gallon containers.

A further object of my invention is to provide a low cost, light weightcontainer which can carry fluid milk or the like without exposing thecontents of the container to airborne bacteria at any time.

A further object of my invention is to provide a completely sanitary,one use container which can be compactly shipped and stored prior to useand which can be readily assembled immediately prior to use.

A further object of my invention is to provide a disposable containerhaving a liquid holding type of liner bag in a cardboard carton andmeans for emptying the contents of the bag through a nozzle havingattached thereto a hose which extends through a flap on one side of thecarton without exposing the contents of the bag to air.

The principles of my invention and the best mode in which I havecontemplated applying such principles will further appear from thefollowing description and the accompanying drawings in illustrationthereof.

In the drawings:

Fig. 10 is a plan view of the inclined support'for use in the bottom ofthe container to provide drainage from and support to the bottom of theflexible liner bag.

My container comprisesa cardboard carton 1 having a false bottom 2 withan inclined surface 3 capable of supporting a flexible liner bag 4. Theflexible bag 4 has secured thereto'a nozzle 5"which projects through anaperture 6 located at the lower end of the inclined surface 3. One endof a hose or tube 7 may be connected to said nozzle Sand the other endled through a cutout 8 in the front end 9 of the false bottom 2 and ledthrough a pull-out flap 10 in one side 11 of the carton 1 injuxtaposition to the cutout 8; The contents of the bag 4 are emptiedthrough the nozzle 5 and hose 7.

The flexible liner bag 4 is preferably made from a section ofpolyethylene which is heat sealed along the bottom edge 12 to form a bagopen'along the top edge 13. The nozzle 5, which may also be formed frompolyethylene, is heat sealed or otherwise attached to the lower portionof the bag 4 at the same time perforating the bag to permit the contentsof the bag to freely flow into the nozzle 5, as illustrated in Figs. 3and 7.

I may, however, permit the skin of the bag to form a diaphragm 14 overthe base of the nozzle 5, as shown in Fig. 6. In this modification, Imay keep the bag 4 completely sealed until the time the bag is to beemptied at which time the operator inserts a pointed instrument (notshown) through the canal 15 of the nozzle 5 to perforate the diaphragm14 and permit the contents of the bag to flow into the nozzle 5.

Normally the cardboard carton 1 and false bottom 2 are shipped to acreamery in flattened condition as illustrated in Figs. 8 and 10. Whenthey are to be used the carton is folded along its normal crease linesso as to form the shape indicated in Figs. 4 and 9. The false bottom isfolded along its normal crease lines so as to form the shape illustratedin the center of Fig. 4 and is inserted in the folded carton 1 so thatthe V-shaped cutout 8 and aperture 6 is adjacent the flap 10, asillustrated in Figs. 2 and 3. Prior to insertion of the false bottom inthe carton, the nozzle 5 attached to the bag 4 is placed through theaperture 6 and the hose 7 firmly attached to the end thereof. The falsebottom 2 and the bag 4 are then inserted into the carton 1 as a unit,the hose 7 being disposed in the void beneath the false bottom 2 untilthe bag is to be emptied. The lower end of the hose 7 has a plug orclosure 26, Fig. 3, thereby sealing the lower end of the bag when thehose is securely attached to the nozzle 5.

After the carton, false bottom and bag are assembled as above described,the bag is filled with milk or other fluid and the top of the bag sealedby a ring 16 or the like, as illustrated in Figs. 3 and 4. The closureflaps 17, 18, 19 and 20 of the carton 1 are then folded over and sealedby a tape 21.

When the sealed container is to be emptied, the flap 10 is pulled openby means of the finger hole 22 and the free end of the hose 7 is fishedout of the void beneath the false bottom 2. The container is then placedin a dispensing cabinet 23, such as illustrated in Fig. 1. Such adispensing cabinet normally has a pinchcock type of apparatus 24 forpinching the hose 7 shut while the weight or handle 25 is in loweredposition. After the container is in position in the dispensing cabinet23, the

='Z free -end oft-thehose-7'is led through the pinchcock 24 and the hoseis severed immediately above the plug or closure 26. As soon as thelower end of the hose 7 has been severed the bag 4 may be emptied merelyby lifting .1tthe'weight 25 thereby'opening thepinchcock 24 andpermitting the milk or other fluid to:fl'ow through the hose 7. Ifdesired .thenozzle Sand the tube 7 may be made as a single unit. Theplug 26 at the end of the tube 7 'will, of course, prevent the contentsof the bag from being emptied prior to removal of the plug or thesevering of -.the end .of the tube containing the plug.

Although the container, may-be used without the false bottom in thecarton,*inwhich case the nozzle 5 can be uHaving described my invention,I claim:

1. A container comprising a disposable carton having :closure flaps atthe top and bottom of said carton, a false bottom having an inclined topsurface and supported by said closure flaps'at the bottom of saidcarton, an aperture in said false bottom near the lower end of saidincline andadjacent one side of said carton, a pullout flap on one sideof said carton providing an opening into said carton below said inclinedsurface, a flexible bag in said carton having a nozzle attached theretoand protruding through said aperture, and a flexible tubeattached 4tosaid nozzle for delivering the contents of said bag to the outside ofsaid container by way of said flap.

2. A container comprising a disposable carton having closure means atthe top and bottom of said carton, an opening on one side of said cartonnear the bottom thereof, an inclined support in said carton having'anaperture at the lower end thereof adjacent said opening, a flexible bagin said carton seated on said inclined support, a nozzle aifixed to saidbag and projectible through said aperture in said support, means forstoring a flexible tube in said carton during storage and transit, oneend of said tube being connected to the end of said nozzle for emptyingthe contents of said bag through said opening to the outside of saidcontainer.

3. A container comprising a carton having closure flaps at the top andbottom thereof, a pull-out flap on one side of said carton near thebottom thereof, a flexible bag in said carton and supported by saidclosure flaps, said bag having a. nozzle projectible through saidpullout flap, and means for sealing said bag and nozzle prior toemptying the contents thereof through said nozzle.
